Abstract (en)

[origin: WO2015015323A1] The present invention relates to a method for coating with metal material a body (1) of ductile iron, comprising the following steps: preparing a body (1) of ductile iron with at least a surface (2) intended to be coated, a thickness of said body (1) being identifiable in a direction orthogonal to said surface (2) intended to be coated, drying by heating at least said surface (2) to be coated, lining a layer of stainless steel on said surface (2) to be coated by pulsed arc welding with stainless steel as filler material, said welding being made directly on said surface (2) to be coated. The invention further relates to a back plate or dies for aluminium die-casting machines comprising at least a body (1) of ductile iron coated with stainless steel, wherein the coating is made by the method according to the claim method.
